Algebraic Geometry Seminar | Birational modifications of elliptic Calabi-Yau degenerations

Time：Fri., 11:00-12:00 am, Mar. 29. 2024

Venue：Jingzhai 静斋 105 | Zoom Meeting ID: 262 865 5007 Passcode: YMSC

Organizer：Caucher Birkar，曲三太，陈炳仪

Speaker：Seung-Joo Lee (Institute for Basic Science)

Abstract:

In this talk, upon discussing aspects of the string landscape, I will motivate and introduce a program for birationally characterizing the infinite-distance degenerations of compact elliptic Calabi-Yau varieties, described in a Weierstrass form. Then, I will report on our main results for elliptic K3 surfaces, which conform with what is known about Kulikov models. If time permits, a recent attempt to generalize the results to 3-dimensional Calabi-Yau varieties will also be discussed.

Locally stable degenerations of log Calabi-Yau pairs
Abstract We study the birational boundedness of special fibers of log Calabi-Yau fibrations and Fano fibrations. We show that for a locally stable family of Fano varieties or polarised log Calabi-Yau pairs over a curve, if the general fiber satisfies some natural boundedness conditions, then every irreducible component of the special fiber is birationally bounded.About the speaker 焦骏鹏，清华...
